Faults:

Nothing mechanical.

Tires that came with the car (Hankook) were absolutely HORRIBLE! Replaced with Nokian All Weather (also purchased winter tires on wheels)

Getting into the front passenger seat is difficult as the grab handle is in a bad location. Needs a handle in the A-pillar as in other Mercedes.

General Comments:

The van has great visibility to the front/sides. Rear visibility is restricted by the seat headrests and the 180-degree doors.

Seats are comfortable up front, but the rear seats are narrow.

Acceleration is brisk, getting up to speed very quickly. Brakes are very good.

Very good on snowy roads with winter tires.

Radio and navigation could be better, although the sound is quite good. I have added a SiriusXM receiver.

Bluetooth is good, but using the way of finding people/places in the address book defeats the idea of hands free. This system is nothing like the phone in our other Mercedes. Finding who you want to call is a big distraction.

We took the 3rd row seats out for more room for dogs, suitcases, etc. Seats come out easily, but are quite heavy.

The van is good, but not as good as the Euro versions. It could be better.
